Question

What are the factors of 42 to find it’s prime numbers and how do I put it in a factor tree

Answer 1

To find the factors of 42, we need to identify the numbers that divide evenly into 42 without leaving a remainder. The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, and 42.

To create a factor tree for 42, we start by finding a pair of factors of 42, such as 2 and 21 and factor each branch until we have prime numbers.

Answer 2

See below

Explanation:

Starting with 42, there would be two branches of 2 and 21 connected to 42. Since 2 is prime, there are no more branches. Since 21 is composite, then two more branches are drawn of 3 and 7 connected to 21. Since 3 and 7 are prime, there are no more branches.

Therefore, the prime factorization of 42 is 2*3*7, and its factors would be 1,2,3,6,7,14,21,42.
